Cranborne Audio 500R8 USB Audio Interface and 8-Slot 500-Series Rack Chassis

Analog Character Meets Digital Precision

Upgrade your studio with convenience and powerful expandability through the 500R8 USB Audio Interface and 8-Slot 500-Series Rack Chassis from Cranborne Audio, a complete studio in a box that provides comprehensive I/O, high-spec digital conversion up to 192 kHz, and the ability to grow your 500-series module collection while being easy to reconfigure on the fly for your needs. With full-featured monitor control and talkback facilities, an 8x2 summing mixer, a powerful low-latency headphone mixer with dual dedicated outputs, and reference-quality audio performance and internal clocking, the 500R8 is an ideal central brain for your studio that can be picked up and carried to your next session.

The eight 500-series module slots deliver 250mA per slot, with 2A total for all slots, ensuring the best possible performance from your precious rack modules. The audio interface features 28 inputs and 30 outputs with high-stability low-latency USB 2.0 and plenty of further options for expanding your connectivity including ADAT (up to 16 channels), S/PDIF, 5-pin MIDI, and Cranborne's proprietary C.A.S.T. ports, which use Cat 5e, Cat 6, or Cat 7 cabling for connecting to breakout boxes to eliminate excess cabling or to increase available channels with modules like the 500ADAT or a second 500R8. The 500R8 includes an external power supply, an IEC power cord, 16 module mounting screws, and an allen key.

Configure 500R8 to suit your desired analog flavor. Fill it full of vintage-style 500 series preamps, when you're recording drums, clean and pristine preamps when you're recording strings, or EQ, compression, and saturation 500-series modules when it's time for mixing.

Connect 500R8 directly to your PC/Mac and capture every last nuance of your analog sources with reference-class AD/DA conversion and superior internal clocking. Effortlessly pass audio between analog and digital worlds without digital artifacts that color and degrade your recordings.

Switch between two sets of speakers (A/B), toggle Mono sum, Mute, Dim, and Talkback facilities with phantom power whilst monitoring the peak level of your mix with 28-segments of LED detail by using the built-in, high-headroom monitor controller. You get push-to-talk activation as well as automatic routing to all headphones. Finally, the front panel controls for all monitor controller functions are illuminated for easy access.

The 8x2 analog summing mixer provides you with +26.6 dBu of headroom, dedicated ADC, and balanced 1/4" outputs. Sum your 8 USB sources through your 500-series modules into the discrete analog mixer and record it back into your DAW as a stereo track. You can also use the C.A.S.T. link port for increasing your summing mixer to a 16x2 using the Cranborne Audio 500ADAT.

Monitor live sources in the analog domain with zero latency using dedicated mix level and pan controls per channel combined with Cranborne's seriously high-powered headphone amps. Use the DAW return blend controls for the perfect tracking mix. Each of the two headphone outputs feature independent blend and level controls.

The 500R8 integrates with all of your analog/digital hardware. Patch in 500R8 with your own converter or integrate your 19" rack gear with dedicated TRS insert jacks per slot.

Mix and match your 500-series modules to find the best combinations during recording, and mixing to help create your own signature, analog sound. Repatch your 500R8 at a flick of a switch.

Dedicated source select switches for each 500-series slot adjusts the signal routing to send analog, C.A.S.T., or USB sources through each of your modules. Bypass unused 500-series slots using 500R8's dedicated slot-bypass switch and you can use all of the available analog paths for recording whilst you continue to build your 500-series collection.

Expandable via C.A.S.T.

Fitted with Cranborne's C.A.S.T. system, the 500R8 is compatible with the N22 and N22H C.A.S.T. breakout boxes that cast away excess cabling spaghetti and offer a cost-effective, low-maintenance, plug-and-play solution to rewire your studio. C.A.S.T. transports 4 channels of balanced, analog audio over shielded Cat 5e, Cat 6, and Cat 7 cable directly to the location where it is needed in your studio.

Create vocal booths, isolation booth, or run our a microphone to the hallway for ambience, C.A.S.T. is the best way to expand your 500R8 and get the most out of your studio space. If you have preamps installed into the 500R8, C.A.S.T. can transport their 48V phantom power through the C.A.S.T. connection via Cat cables and directly to condenser or active microphones connected at the end point. C.A.S.T. is completely plug-and-play and works at distances up to 328' for maximum flexibility and convenience.

Versatile Ergonomics

The 500R8 is not only versatile in function, it also has a convenient physical design. With the included, prefixed 19" rack ears, you can easily pick up the 500R8, carry it to a recording session, and even mount it directly onto a traditional equipment rack. Now you have 8 rack modules taking up only 4 RU of rack space.
